PL903xxx Revision 1.0 General Description Features The PL903xxx series is a small form factor, highperformance OTP-base device and a member of MicrelвЂ™sJitterBlocker, factory programmable jitter attenuators. TheJitterBlocker product family cleans deterministic jitter byattenuating spurious components in the phase noise,thereby improving the phase jitter and the overall phasenoise. The PL903xxx is capable of reducing multiple picoseconds of phase jitter in a clock to a level below 1psRMS,making that clock usable for many more applications. The PL903xxx operates on a single 2.5V or 3.3V supplyand is housed in a small QFN package for a broad rangeof applications.Input clock frequencies up to 200MHz can be filtered andfrequency translation allows for output clock frequenciesup to 840MHz. Datasheets and support documentation are available onMicrelвЂ™s web site at: www.micrel.com.
